Evaluation of the Quantity of Extruded Debris through the Apical Foramen Using Optimum Glide Path Motion: An ex vivo study

Abstract

Objectives: The study was evaluated apically extruded debris from teeth that were instrumented with full-sequenced files using a new kinematic technique (optimum glide path motion). Materials and Methods: The specimens were divided into four groups (n = 18) based on the kinematics of rotation motion (RM), 90° optimum glide path (OGP) motion, 90° clockwise (CW)–90° counterclockwise (CCW) motion, and 90° CW–120° CCW motion. Pre-weighed Eppendorf tubes were used to collect debris. The weight of the dry extruded debris was calculated by deducting the initial tube weight from the end weight. The Kruskal–Wallis test and the least significant difference for pairwise comparisons test were used to statistically assess the data (P < 0.05). Results: In comparison to the RM, the 90° OGP motion extruded the least quantity of debris, which was statistically significant (P < 0.05). Conclusions:The findings suggest that a 90° OGP motion delivers the best results regarding extruded debris through the apical foramen. Clinical Relevance: Within the limitations of the study, Optimum glide path (OGP) motion resulted in less debris extrusion compared to the rotation motion. Clinical application of full-sequenced rotary systems in OGP motion may be reliable and beneficial.
